T-Mobile Polska launches long-haul 400GbE service with Ciena

First 800G network in Poland brings faster speeds, greater capacity for a digital future.

T-Mobile Polska, one of the largest mobile operators in Poland, selected a coherent optical solution from Ciena for its high-performance, flexible 800G network. Leveraging Ciena’s technology, T Mobile Polska will offer a new long-distance 400 Gigabit Ethernet (400GbE) service to its enterprise, content provider, and wholesale customers, to address exponential traffic growth brought on by omnipresent remote work, learning, and entertainment.


To satisfy skyrocketing bandwidth demands from data services and cloud applications, T Mobile Polska is deploying Ciena’s WaveLogic 5 Extreme coherent optics over a 6500 fully flexible colorless, directionless, and contentionless photonic system.


Digitization is a driving force for growth in the business sector. The Ciena solution will be used to provide high-capacity 500Gbps–800Gbps wavelength connectivity, low latency, and reliability, making it possible to transport services such as 5G, cloud, and data center interconnect (DCI) at a lower cost per bit. Additionally, encryption capabilities allow for secure transmission of sensitive financial and government data.


The network is managed by Ciena’s Manage, Control and Plan (MCP) domain controller, allowing for operational efficiency and quick turnup of new services. With MCP, T Mobile Polska can rapidly identify, troubleshoot, and repair any issues that arise.
